Product Overview
The Motorola MC14094BCP combines an 8-stage shift register with internal data latches and three-state outputs in a standard 16-pin plastic DIP. Part of the 4000-series CMOS logic family, it accepts serial data input, shifts each bit across eight successive clock cycles, and outputs all eight stages in parallel. Independent latch controls hold output data stable during active shifting, and three-state buffers permit direct integration into multiplexed bus architectures.
Key Features
- 8-bit serial-in, parallel-out (SIPO) shift and store architecture with internal data latches
- Three-state parallel outputs (Q1 through Q8) for direct connection to shared data buses
- Dual serial outputs: QS for high-speed cascading on positive clock edges, and Q'S for negative clock edges
- Wide DC supply operating voltage range from 3.0 V to 18.0 V
- Built-in input diode clamp protection across all logic lines
- Output drive rated for two low-power TTL loads or one low-power Schottky TTL load
- Through-hole 16-pin plastic dual in-line package (PDIP-16, Case 648)
- Pin-for-pin compatible with industry standard CD4094B and CD4094BE devices
Applications
- Expanding microcontroller output capability to drive multiple discrete indicators, relays, or segment displays using minimal I/O pins.
- Cascading multiple shift registers in high-speed or low-speed serial-to-parallel telemetry chains.
- Servicing legacy industrial control hardware, laboratory instruments, and vintage synthesizer boards built with 4000-series CMOS logic.
Frequently Asked Questions
Is the MC14094BCP drop-in compatible with CD4094B ICs?
Yes. The MC14094BCP shares standard pin assignments, supply voltage tolerances, and functional logic with CD4094B and CD4094BE integrated circuits.
What supply voltage does this shift register support?
The device operates reliably across a wide DC supply range of 3.0 V to 18.0 V, making it versatile for both standard 5 V logic rails and higher-voltage 12 V or 15 V control circuits.
Can I buy only the quantity needed for my board, and is volume pricing available?
Yes. You can order an individual chip for a single repair or select multiple units for a project build. Buying more pieces costs less each, and the price-break table on this page shows what each quantity costs. Orders ship for an $8 flat rate, free once the order passes $28, and leave our Idaho warehouse the same or next business day.
Solid 4000-series CMOS logic from Motorola that turns a lean serial stream into eight clean parallel lines. Plug it into your socket and let the shift register take the bus.
